Point stands though. Voorveld, middenveld, achterveld works in Dutch. Don't know what these German words technically mean and so they might have a different translation, but you can / it is common to make this type of compound.
According to <https://www.dict.cc/?s=achter>, not only is it northern german, but also "sailor language"! :D English is similar, having "aft" for sailors to say "rear". I know boat people have specialized terms but never thought of it as sailor speak but rather like any other jargon. For some odd reason, the dictcc page also mentions the random fun fact that "achter" is Afrikaans, ignoring where Afrikaans got it from (or rather, who forced it upon them)
